The band also enlisted an array of guests to help achieve their vision. The one and only legendary Phil Anselmo lends his throat to "The Prophets Of Loss" while recent signee to his Housecore Records label, fellow San Diegan and friend of the band, Author & Punisher, brings forth the industrial damnation as an intro to the track "Plagueborne". Additionally, Germany's metal misanthrope, Jürgen Bartsch of Bethlehem, lends a spoken word piece in his native tongue to the apocalyptic final track "Pacific Grim".
Travis Ryan comments: "Dave is a bonafide producer. He's got a lot of great ideas and this time we heard him out pretty religiously because making Monolith Of Inhumanity had worked out so well. We've always kind of co-produced our records with whoever we brought in, but these last two we did a lot more listening to what he had to say rather than just sticking with what we were saying. Sometimes we shot down his ideas and vice versa, but that discussion was always beneficial. He basically becomes the fifth member of the band at that point, and I think that kind of relationship is the best way to get anything out of anybody."

Really liked those melodic pitched-screams that Travis does - he's really good at fitting them in with the music.
